Are Chelate Rings Aromatic? Calculations of Magnetic Properties of Acetylacetonato and o-Benzoquinonediimine Chelate Rings
(American Chemical Society (ACS), 2007)
The aromaticity of the chelate rings of acetylacetonato (acac) and o-benzoquinonediimine (bqdi) ligands was
investigated theoretically by calculating nucleus-independent chemical shifts (NICS). The calculations were ...
Influence of thermal treatment on phenolic compounds and antioxidant properties of oak acorns from Serbia
(Elsevier, 2007)
The aim of the present work was to investigate and compare phenolic compounds and antioxidant activity of methanol extracts of Quercus robur and Quercus cerris acorn kernels obtained before and after thermal treatment. ...
Deoxycholic acid-derived tetraoxane antimalarials and antiproliferatives
(American Chemical Society (ACS), 2007)
The synthesis of deoxycholic acid (DCA)- and cholic acid (CA)-derived mixed tetraoxanes revealed that N-(2-dimethylamino)ethyl derivatives are potent antimalarials in vitro and in vivo. The tetraoxanes presented in this ...
Kinetics and mechanism of the formation of poly[(1,1,3,3- tetramethyldisiloxanyl)ethylene] and poly(methyldecylsiloxane) by hydrosilylation
(Wiley-Blackwell, 2007)
The kinetics of the formation of poly(carbosiloxane), as well as of alkylsubstituted poly(siloxane), by Karstedt's catalyst catalyzed hydrosilylation were investigated. Linear poly(carbosiloxane), poly[(1,1,3,3-tetrameth ...
Far infrared properties of sintered NiO
(Elsevier, 2007)
Far infrared reflection spectra of NiO polycrystals sintered at 1100 °C for various times (30–240 min) were measured at room temperature using a FTIR Spectrometer—Brucker 113V. The measured spectra depended on the sintering ...
Fluctuations of the number of particles and mass adsorbed on the sensor surface surrounded by a mixture of an arbitrary number of gases
(Elsevier, 2007)
In this paper the theory of the adsorption and desorption process of an arbitrary number of gases on the sensor surface is presented. It is assumed that the sorption follows the Langmuir isotherm. The exact expressions are ...
A refined pharmacophore identifies potent 4-amino-7-chloroquinoline-based inhibitors of the botulinum neurotoxin serotype A metalloprotease
(American Chemical Society (ACS), 2007)
We previously identified structurally diverse small molecule (non-peptidic) inhibitors (SMNPIs) of the botulinum neurotoxin serotype A (BoNT/A) light chain (LC). Of these, several (including antimalarial drugs) contained ...
Cell wall invertase immobilization within calcium alginate beads
(Elsevier, 2007)
Yeast cell wall invertase (CWI) was immobilized within calcium alginate beads. The result of entrapment was the complete immobilization of all the added CWI. Three types of biocatalysts were prepared: CWI-S, CWI-155 and ...
Synthesis and antioxidant properties of fullero-steroidal covalent conjugates
(Oxford : Pergamon-Elsevier Science Ltd, 2007)
Four new fullero-steroids were synthesized starting from gamma-aminobutyric acid (GABA)-incorporated fulleropyrrolidine and corresponding sterols. The synthesis, characterization, preliminary study on in vitro antioxidant ...
Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Springer Heidelberg, Heidelberg, 2007)
Introduction. In this work, sediments of the River Tisa (Tisza) are studied to assess their environmental pollution levels for some major heavy metals, as well as to predict the investigated elements' mobility on the basis ...
